As Part of a Narrative
One author
Stroop (1935)
Two authors
Strafford and Gurney
(2004)
Three to five
authors
First citation:
Risko, Stolz,
and Besner
(2005)

authors
Smith et al.
(2004)
Subsequent citations:
(Risko et al., 2005)*
Exceptions & Special Cases
When two
works with
three or more
authors shorten
to the same
abbreviation, use
enough authors
to distinguish
between them.
• (Smith, Jones, & Madson,
2004) and (Smith,
Johnson, & Jones, 2004)
• Shorten to: (Smith,
Jones, et al., 2004) and
(Smith, Johnson, et al.,
2004)
• DO NOT change
the order of the
authors! They must
be represented as
they are credited in
the study.
• (Smith, 2005a) and
(Smith, 2005b)
• Works will be listed
When two
as they appear in the
different works
reference pages
have the same
author and the
same year:
When two
different
authors have
the same
surname:
• (A. Smith, 2005) and
(C. D. Smith, 1995)
• Even if the date of
publication differs,
distinguish between
the two authors by
including first initials
When Page Numbers Are Not
Available
If paragraph numbers are
visible (numbered), use
them in place of page
numbers.
If the document includes
headings and neither paragraph
nor page numbers are visible,
cite the heading and the
number of the paragraph
following it.
When headings are too
unwieldy to cite in full, use a
short title enclosed in
quotation marks.
• (Anderson & Jones, 2007, para. 5)
• (Anderson & Jones, 2008, Discussion section,
para. 2)
• (Anderson & Jones, 2008, “Common
Symptoms,” para. 1)
• (Full heading is “Common Symptoms of
Ailments Such as the Stomach Flu”)
More Citation Rules
Multiple studies in one
citation
 By the same author:
•
One author cited multiple
times in one paragraph
 If there is no possibility of confusion,
only cite the year in the first citation*
 By multiple authors:
•
If one citation is more significant, it may
be listed first, with a phrase such as
“see also” inserted to separate the
others: (Zimmerman, 1993; see also
Branch, 1980; Smith, 2001)
Citation Rules, Continued
 Anonymous Authors

 Unknown Authors

 Group as Author
 When a group or corporation has a long name and a common or easily
understood abbreviation:
 First citation: (National Institute of Mental Health [NIMH], 2000)
 Subsequent citations: (NIMH, 2000)
Citation Rules, Continued
 Personal Communications
(i.e. letters, interviews, memos, emails, telephone conversations, etc.)

 Writing Tip: Note that the first initials ARE used for personal
communication
 Note: do not include personal communications in the reference list
 Unknown Date


Citing Web Pages
 In-text citation of web-based material follows the same rules :


 Direct quotes of web-based documents:
Websites have no page numbers!
 Cite the paragraph number if possible:
 Cite the sub-section and paragraph number if possible:
 Note: when a web-based source is printed, the top of the page will include a number
for the purpose of printing, i.e. “1 of 3.” These are NOT the page numbers of the
document and should not be cited as such.
Block Quotes
 Required for quotes longer than 40
words
 Inset by two tab spaces (or one inch)
on both the right and the left.
 Double-Spaced
 When a quotation is indented in this
way, quotation marks are not needed.
 Usually, quotations longer than four
lines require block quote formatting.
(Author, date, p. #)
Reference List: Basics
 Reference lists should be alphabetized by the
last name of the first authors listed.
 Remember, you can not change the order of
authors within the study!
 Nothing precedes something:
Green, E. C. (2000).
Greene, B. A. (1994).
Harrison, M. R. (2004).
Harrison, M. R., & Blake, C. D. (2001)
NOTE:
First Initials ARE used on the Reference
page!
The DOI: Digital Object
Identifier
 The DOI is like a social security number for a source. It is meant to help
readers find the exact source you are referencing.
 All DOI numbers begin with a 10 and contain a prefix and a suffix separated
by a slash.
 If the source has a DOI, cite it after the rest of the citation is finished:
 Brownlie, D. Toward effective poster presentations: An annotated
bibliography. European Journal of Marketing, 41(11/12), 1245-1283.
doi:10.1108/03090560710821161

 These journals are paginated by
volume, and do not require the issue
number in the reference citations
Paginated by issue
Journals whose issues each begin on page
one require the issue number in the
reference page to specify the issue in
which an article appears:
 [An article listed in volume 23, page
189, would not tell a reader which
issue contained the article]
